Is your Nissan running rough, stalling, or having trouble starting? A faulty crankshaft position sensor could be the issue. This Oskkude sensor is a direct replacement for part number 23731-EA20D (or 23731EA20D). It fits a bunch of Nissan trucks and SUVs including the 2005-2018 Frontier, 2005-2012 Pathfinder, 2005-2015 Xterra, and the 2012-2020 NV1500/2500/3500 vans. This little sensor is crucial – it tells your engine's computer exactly where the crankshaft is and how fast it's spinning, which controls fuel injection and ignition timing. This one is made with quality materials to meet or exceed OEM specs for reliable performance. Installation is usually straightforward, but if you're not comfortable working on engines, we recommend having a pro do it. Always double-check your vehicle's exact year, model, and engine, and compare the old part number before buying to ensure a perfect fit.
